Question

What is the surface area of the cylinder with height 8 and radius 2? Round your answer to the nearest thousandth.​

Answer 1

Answer:

surface area of cylinder is 126cm²

Step-by-step explanation:

Height of a cylinder is 8cm

Radius of a cylinder is 2cm

surface area = ?

surface area of cylinder= 2πr(r + h)

=2×22/7×2(2+8)

=44/7×2(10)

=44/7×20

=880/7

=125.71

Answer 2

A = 2πrh + 2πr² π=3.14

• (2 x 3.14 x 2 x 8) + (2 x 3.14 x 2x2)
• 100.48 + 25.12
• A =125.6
